SPECIFICATION forming part of Letters-Patent No. 725,411, dated April14, 1903.

Application filed January za eoa' seraino.140,380. (No mans UnitedStates, and residents of Ironton, in' the county of Lawrence and Stateof Ohio,"

have invented a new and Improved Axle-Gage,

of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for gaging railway-caraxles to ascertain whether or not the axle has become bent or sprung byaccident or bypressure in traffic, the object being to provide a devicefor this purpose of simple and inexpensive construction that may beeasily handled by a traininspector or other person.

We will describe an axle-gage embodying our invention and then point outthe novel features in the appended claims.

Reference is to be had tothe accompanying drawing, forming a part ofthis specification, in which the figure is a side elevation of anaxle-gage embodying our invention.

The gage comprises a frame or yoke 1, in] the downwardly-turned ends ofwhich arescrews 2 for engaging the lathe-centers of a car axle. Movablevertically through an opening in the center of the frame or yoke is agage-bar 3, designed to indicate the trueness' of. the axle. On oppositesides within the yoke or frame the said bar is provided withratchet-teeth 4:, designed to be engaged by spring-pressed pawls 5, andon the outer end nals or axle.

In the operation the points of the screwsv of this bar is a pointer 6,movable along a graduated plate 7. The frame or yoke is provided withscrews 8, designed to engage upon the periphery of the wheels toindicatewhether or not they have slipped on the jour- 2 are to be inserted inthe lathe-centers of the axle, and then by moving the wheels over afloor ora track and by holding the frame or yoke in its verticalposition by mean s'of.

handles 9 and while the screws 8 are engaged with the wheels and the rod3 engages with the axle the said movement will indicate the trueness ofthe axle and wheelsthat is, should the axle be bent or sprung, and 'pro7 vided thebar 3 shall have been placed inen- 5o gagement with the lowerportion, the said bar will be raised as the axle rotates and the amountof deflection will be indicated on the scale-plate 7. Y

' Of course if'the end-of the rod 3 shall have been placed on the higherportion'of the bent axle the-lower'portion will be indicated by y thesight-opening between the bar and th axle. I

Having thus des'cribedour invention, we 7 claim as new and desire tosecure by Letters 'Patent 4 1. An axle gage comprising a frame or yoke,centering-screws in the downwardly-extended ends .ofsaid frame or yoke,a vertically-movable bar arranged inthe frame or yoke, a pointer on saidbar, and a scale-plate along which the pointeris moved.

2. An axle-gage comprising a yoke, centeri'ng-screws in thedownwardly-extended ends of said yoke, a gage-bar; vertically movable inthe said yoke, a spring-pressed pawl engaging with said bar, and -a,gage-plate alongwhichthe said bar is movable.

' '3. An axle-gage comprising a yoke, e'entering-screws inthedownwardly-extended ends of said yoke,- an'axle-gage bar movable insaid yoke, and wheel-gage devices adjustable in said yoke. v

p 4. An axle-gage comprisingayoke, centering-screws in thedownwardly-extended ends of said yoke, handles onthe yoke, an axle gagebar movablevertically through the yoke, pawls for holding said bar, apointer on the bar, a gage-plate along which the pointer is movable, andwheel gage screwsl carried in the yoke;

In testimony whereof=we havesigned our names to this specification :inthe presence of the subscribing witnesses.
